The Allen Bradley 872C-A4N12-R3 operates as an inductive proximity sensor, engineered to excel in various sensing applications. Measuring a barrel diameter of 12 mm, it is compact and suitable for tight spaces. The nominal sensing distance achieved by this device is 4 mm, making it effective for applications where close-range detection is required.

It functions as a 2-wire AC type sensor, suitable for detection tasks under specified voltage requirements. The sensor can effectively operate at voltages ranging from a minimum of 20 VAC to a maximum of 250 VAC. Its output arrangement provides a normally open (NO) contact configuration, enhancing its functionality within control systems.

The construction of the sensor features a tubular body design made from nickel-plated brass, ensuring durability and resistance to environmental factors. Connectivity is accomplished through an AC Micro quick-disconnect interface, allowing for flexible installation and maintenance. Additionally, the connection media consists of a 3-pin PVC cable that is yellow in color with a braided shield, measuring 2 meters in length. The unshielded design further contributes to the simplicity of this sensor, making it a practical choice for a variety of industrial applications.
